It may look long and sleek like a full sized luxury saloon, but that is just a part of this concept car’s appeal. Stretching no further than the length of a BMW 3 Series, the Jaguar B99 Concept by design-house Bertone is believed to be a glimpse at what Jaguar is planning as a successor to the failed X-Type.

These renderings of the car have been leaked ahead of its official debut March 1st at the Geneva Auto Show, giving a hint at how Jaguar intends to style its new entry-level luxury sports sedan.

According to recent reports, however, this new model won’t be the first new Jag to debut, with a rumored XE compact sports car planned for next year.

Look for live photos of the B99 Concept March 1st with AutoGuide’s complete coverage of the 2011 Geneva Auto Show.
